POWER IBC04-36S12 th Data Sheet 1/8 Brick Bus Converter Total Power: 50 W Input Voltage: 18 - 60 V Single Output: 12 V SPECIAL FEATURES ƒ Ultra wide input range ƒ Optimised for contact cooling ƒ Low ripple and noise The IBC04-36S12 is the latest wide-range input isolated DC-DC converter specifically designed ƒ Fixed switching frequency to supply non-isolated converter architectures. It operates from an ultra-wide input range of 18 Vdc to 60 Vdc and provides a regulated output voltage of 12 V. The output is rated to a ƒ High capacitive load capability power level up to 50 W. ƒ Pre-bias start-up capability Its protection features include non-latching OCP and OTP with non-latching OVP. It also has an ƒ Basic insulation system enable pin on the primary side of the converter. The unit is an open frame design that is ƒ Through-hole termination optimised for either contact-cooled applications or forced airflow applications. ƒ Open frame construction Electrical Specifications SAFETY Input ƒ UL 60950-1 Input range 18 Vdc to 60 Vdc ƒ CE Mark Input surge 100 V for 100 mSec Efficiency 92% typ (> 89.5% @ 2.8 A out - 4 A out & 18 Vin - 55 Vin) Control Enable: TTL compatible positive or negative enable Output Output voltage 12 Vdc Output current 0 A to 4 A Ripple and noise 50 mV rms, 200 mV pk-pk Regulation (total error band) ±5% Vout Over current protection 5 A Over voltage protection 15 V Output overshoot 10% (Iout =Imax, Temperature = 25 °C) Over temp protection 115 °C Typical Output capacitance 0 µF to 2000 µF Fixed switching frequency 300 KHz Nominal Switching frequency (265 KHz min to 335 KHz Max at 25 °C) Isolation voltage 1500 Vdc Transient response 600 mV deviation 600 uS recovery (25% - 75% Iout) UVLO Turn-on 18 Vdc UVLO Turn-off 16 Vdc Environmental Specifications Storage temperature -40 to +105 °C Operating temperature -40 to +85 °C (ambient) MTBF >1 Million hours target IBC04-36S12 Data Sheet Mechanical Specifications Pin # Designation PIN 1 +V IN PIN 2 Enable
